Add juice to a saucepan and gently and evenly sprinkle gelatin over the juice. Gently mix with a spoon and let the mixture sit for 5 minutes. Do not heat up the mixture yet.
Add honey to the mixture and turn the stove to medium-low heat. Make sure the mixture doesn't boil. As the mixture warms up, it will turn into liquid.
Turn off the heat and carefully pour the liquid into the molds. Gummy bear silicone molds come with a few droppers, but I prefer to pour the liquid into the molds using a glass measuring cup. Sometimes using the droppers can create a lot of bubbles.
Let them sit out on the counter for an hour before putting them in the fridge.
Let them set in the fridge for a few hours, then pop the gummies out of the molds and enjoy! Store leftovers in the refrigerator.
Notes
Sprinkle the gelatin over the juice mixture rather than dumping it in all at once.
Add some lemon juice for a little tartness.
Avoid juices like papaya, pineapple, kiwi, or mango, as they contain an enzyme that can prevent the gelatin setting up.
If you don’t want to use honey, you should be able to substitute maple syrup.
Fill the silicone molds fully for the best results.
When transferring the gummy mixture to the refrigerator, I like to set my molds on a cookie sheet or similar tray just in case some of the liquid spills out.
